Am trying to access camera roll on my react native app and it not giving back feedback

This my code

onImageUpload = async () => {
const {status: cameraRollPerm} = await PermissionsAndroid.askAsync(
PermissionsAndroid.PERMISSIONS.CAMERA_ROLL,
try{
if (cameraRollPerm === 'granted') {
let pickerResult = await ImagePicker.lauchImageAsync({
allowsEditing: true,
aspect:[4,3]
});
console.log(
'ready to upload... pickerResult json:'+ JSON.stringify(pickerResult)
);

I tried

await PermissionsAndroid.request(
PermissionsAndroid.PERMISSIONS.CAMERA,
